iStock/Thinkstock(PHILADELPHIA) -- Autopsy reports were released in the case of a missing woman who was found in a parked car in Philadelphia.

The autopsy report showed "no visible sign of injury" on the body of 22-year-old Nadia Malik of Marple Township, Pennsylvania.

Malik's body was found Thursday near Philadelphia's main train station and had a number of parking tickets on the window before and after it was towed for snow removal.

According to ABC's Todd Ant, when Marple Township police chief Thomas Murray was asked why no one saw her inside the car, Murray said "she was covered up pretty good." The car also reportedly had deep-tinted windows.

Malik allegedly had a volatile relationship with her boyfriend, but he hasn't been charged in the case.
